PyQt5 QDoubleSpinBox – Setting Prefix
In this article we will see how we can set prefix to the QDoubleSpinBox. A prefix is an affix which is placed before the stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix un- is added to the word happy, it creates the word unhappy. A string can be added infront of the double spin box value.
In order to do this we will use
setPrefix
method with the double spin box object.Syntax : dd_spin.setPrefix(text)
Argument : It takes string as argument
Return : It returns None
Below is the implementation
# importing libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGui from PyQt5.QtGui import * from PyQt5.QtCore import * import sys class Window(QMainWindow): def __init__( self ): super ().__init__() # setting title self .setWindowTitle( "Python " ) # setting geometry self .setGeometry( 100 , 100 , 500 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for components def UiComponents( self ): # creating double spin box d_spin = QDoubleSpinBox( self ) # setting geometry to the double spin box d_spin.setGeometry( 100 , 100 , 150 , 40 ) # setting prefix d_spin.setPrefix( "Value : " ) # step type step_type = QAbstractSpinBox.AdaptiveDecimalStepType # adaptive step type d_spin.setStepType(step_type) # creating a label label = QLabel( "w3wiki" , self ) # setting geometry to the label label.setGeometry( 100 , 200 , 300 , 80 ) # making label multi line label.setWordWrap( True ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
